If you want any informed feedback then you should post the diagnostics zip file (obtained via Tools->Diagnostics.

Can confirm the same behaviour.

Sep 23 08:05:23 Helion emhttpd: unclean shutdown detected

 

I see the same thing occasionally in the 6.4 Series, where even on a clean shutdown for some reason the system thinks its unclean.

I see the same thing occasionally in the 6.4 Series, where even on a clean shutdown for some reason the system thinks its unclean.

Could it be because of a Windows 10 VM that was running before the shutdown and was installing updates? Right before the system was shut down, the Windows 10 VM screen text went from something along the lines of "Configuring updates... 30%" to "Shutting down...". Could it be that because of the VM not being stopped prior the shutdown process, unRAID thinks it is unclean?

@Squid Thanks your info. I also found "unclean shutdown detected" in my system. But I think it is false detect.


After 1st PQ auto check, I stop it and some days later perfortm a fully check and no any error report.

 

My system was simple, no VM / docker, just a file server. It is headness and on demand power on/off by passing power-buttom. So all data disk usually in standby and will auto wakup in  shutdown subroutine.

 

From now on, I set "Shutdown time-out:" from 60 to 120, I hope this will solve my problem.

 

I am a guy who quite concern the data integerity, all disk will manual check parity monthly, all file have hash mark by FIP and Checksum suite. :x

 

In past time, all parity check also health with linear result.

Is there a resolution to this? I have upgraded to 6.4 and every single time I perform a reboot the server claims the last shutdown was unclean. I have increased the shutdown timeout to 120 seconds but am still experiencing the issue.

Have you tried stopping the array and then only when it is successfully stopped shutting down/rebooting the server?   If the array will not successfully stop then you need to look into what is causing that to happen.

 

If you have topped the array successfully and you still get a parity check on reboot then this would suggest that there is some sort of problem with the USB stick that is preventing unRAID from updating it to say that stopping the array was successful.

Mine seems no problem now, FYR.

Array fails to stop manually through the GUI. It seems the array is waiting for the LibVirt.img file on the cache pool and never exits. Any ideas?

Any running VM?
